kubeadm token generate

Synopsis

This command will print out a randomly-generated bootstrap token that can be used with
the “init” and “join” commands.

You don’t have to use this command in order to generate a token. You can do so
yourself as long as it is in the format “[a-z0-9]{6}.[a-z0-9]{16}“. This
command is provided for convenience to generate tokens in the given format.

You can also use “kubeadm init” without specifying a token and it will
generate and print one for you.
